Unisyn Enterprises — refund of my money of rs.1710/-

Address:

Hyderabad, Andhra Pradesh, 500020

Dear sir,
I have paid rs.1710/- (1400+310) on 10.07.2019 to unysyn enterprises (Order id[protected]/order form no. 349259) thru pay tm towards new tata sky connection with one month subscription free.
After four days i have called their representative mr ramachandra reddy about the new connection. Later also so many times called. But they have failed to install new connection. As they have failed to install new tata sky connection, during last week july'19, i told their representative mr ramachandra reddy to cancel the order and refund us.
Now even after one month also i didn't get my money of rs.1710/-.
I request you to kindly intervene into this issue and advise them to refund my money of rs.1710/-.
